TORONTO — Trump International Hotels Management LLC and Four Seasons Hotels and Resorts suffered data breaches after a cyber-attack compromised Sabre Corp.’s central reservation system.

The breach is part of an attack on Sabre’s systems disclosed in May. Sabre’s reservation systems are used by approximately 32,000 properties worldwide.

At Four Seasons, the security breach involved unauthorized access to certain guest information associated with a subset of hotel reservations processed through Sabre’s SynXis Central Reservations System (CRS) between Aug. 10, 2016 and March 9, 2017. Sabre confirmed the issue has been contained and the unauthorized access has been revoked, but some guest information may have been compromised as a result of the incident.

In a notice on the Trump Hotels’ website, the company stated the attack compromised card-payment details at 14 of its properties. The information compromised included payment card numbers and card security codes for some of the hotel chain’s reservations processed through Sabre’s central reservation system.
